Abstract
A phenomenological study was undertaken of the stress corrosion cracki ng (SCC) of type 304L (UNS S30403) austenitic stainless steel (SS) in boiling 44 wt% magnesium chloride (MgCl2) aqueous solution, From the m orphological information available on the specimen surface after const ant elongation rate testing (CERT) and taking into account the real cr ack shapes, initiation could be modeled using a staircase function, wi th incubation time and saturation crack density depending upon elongat ion rate. The propagation rate of a given crack was found to be a shar ply decreasing function of the density of deeper cracks.
